Factor was among those who traveled with Paul to Israel on his recent trip.

Paul is the featured speaker at the Charleston Meeting, along with National Rifle Association President David Keene. Paul recently defended the NRA against criticism from New Jersey Gov. Chris Christie over a Web video invoking President Barack Obama’s children.

Paul has made no secret of his possible interest in a 2016 presidential run. The timing and symbolism of his South Carolina visit is unmistakable.

In addition to the Charleston event, Paul has taken other traditional steps to prepare for a presidential campaign. He has visited Iowa and New Hampshire during the past year and recently returned from a trip to Israel.

South Carolina Republican Party Chairman Chad Connelly accompanied him on the overseas trip.
